Transgenic tombstones.

As green burial become more popular, Archinect links to Biopresence, an art collaboration by Shiho Fukuhara and Georg Tremmel:

Biopresence creates Human DNA trees by transcoding the essence of a human being within the DNA of a tree in order to create "Living Memorials" or "Transgenic Tombstones". Biopresence is collaborating with scientist and artist Joe Davis on his DNA Manifold algorithm, which allows for the transcoding and entwinement of human and tree DNAs. The Manifold method is based on the naturally occurring silent mutations of base triplets, this means it is possible to store information without affecting the genes of the resulting tree. Biopresence Human DNA Trees do not modify the genes of an organism. Therefore, they are not genetically modified organisms (GMOs).
